Macromolecules in Whole Urine that Promote Calcium Oxalate and Phosphate Crystal Formation
Qualitative studies1 have shown that Tamm-Horsfall mucoprotein (T-H) increases both calcium oxalate and calcium phosphate crystals formed when dilute whole urine is rapidly evaporated. This was confirmed quantitatively for calcium oxalate2 but on addition of T-H to urinary ultrafiltrates the recovery of both crystal types formed was incomplete suggesting that there might be in urine a second macromolecule crystal promoter. This possibility is explored.
